| 中文摘要 | 研究了掺铒TeO2-ZnO-PbCl2碲酸盐基氧卤玻璃在977nm激光二极管抽运下的发光和上转换发光特性，结果发现除红外1．53μm^4I13.2→^4I15/2发光外(荧光半高宽高达69nm)，该玻璃还存在很强的^2H11/2→^4I15/2(527nm)，^4S3/2→^4I15/2(549nm)和^4R9/2→^4I15/2(666nm)可见上转换发光．应用Judd-Ofelt理论计算得到玻璃强度参数Ω1(t=2，4，6)分别为Ω2=5．87×10^20cm^2,Ω4=2．08×10^2-cm^2，; We report on fluorescence and upconversion emissions of Er3+ -doped TeO2-ZnO-PbCl2 tellurite-based oxyhalide glasses under 977nm laser diode excitation. A strong 1.53mum emission from I-4(13/2 -->) I-4(15/2) transition with a full width at half maximum of similar to 69 nm, and three intense infrared - to - visible upconversion emissions at 524, 546 and 668 nm, corresponding to H-2(11/2) --> I-4(15/2), S-4(3/2) --> I-4(15/2) and F-4(11/2) --> I-4(15/2) transitions of Er3+ ions, respectively, have been observed under 977nm excitation and the mechanisms involved have been explained. The intensity parameters Ohm(t) (t = 2,4,6) of Er3+ -doped TeO2-ZnO-PbCl2 oxyhalide glasses have been calculated according to the Judd-Ofelt theory, and the results are Ohm(2) = 5.9 x 10(-20) cm(-2), Ohm(4), = 2.1 x 10(-20) c(m-)2 and Ohm(6) = 1.2 x 10(-20) cm(-2), respectively. The emission cross-section has also been calculated from the absorption crosssection and the emission spectrum by using the McCumber theory. The maximum emission cross-section is 8.75 x 10(-21) cm(-2) at 1.53mum. Our results indicate that TeO2-ZnO-PbCl2 oxyhalide glasses are promising candidates for optical amplifiers and upconversion lasers in comparison with the glasses such as silicate, phosphate, and fluoride glasses. |
